Phenotypes of T-DNA Insertion Lines of Multiple eIF5B Homologs.

(A) Growth and development of 4-week-old mutants under normal conditions. hot3-1, hot3-2, eif5b2 (SALK_148816), eif5b3 (SALK_143304), and eif5b4 (SALK_056578) are shown.

(B) The 2.5-d-old dark-gown seedlings were treated by heat stress (A>45°C/1 h: acclimation at 38°C for 1.5 h and 22°C for 2 h, followed by 45°C for 1 h). Hypocotyl elongation was measured before (blue bars) and 2.5 d after (red bars) heat treatment. Data are means ± se (n = 12).

(C) Six-day-old seedlings were subjected to heat stress (AC>45°C/3 h: acclimation at 38°C for 1.5 h and 22°C for 2 h, followed by 45°C for 3 h) and photographed 5 d later.
